The Complete History of the Earth: Proterozoic Eon

Overview

This week I move forward with the history of the Earth and enter the turbulent time known as the Proterozoic Eon. This is going to cover everything else left in the time that is considered the "Pre-Cambrian" and will take us through the rise and fall of empires (of Cyanobacteria) as well as several times when the Earth literally froze over! However, during a quiet time in Earth's history known by scientists as "The Boring Billion" a new bunch of lifeforms would evolve that would forever change life on this planet.
